🌾 Sow directly in the garden — Genovese Basil is not usually started indoors.
Do not start indoors; sow seeds directly into the garden only after all danger of frost has passed and soil temperatures are warm.
Soil, care & harvest
Prepare loose, well-drained soil with a pH between 6.0 and 7.0. As a warm-season crop, start seeds indoors only after the last spring frost when nights are mild. Sow seeds about 1/4 inch deep; they typically germinate within five to ten days once warmth is established.
Space plants 12 to 18 inches apart to ensure good air circulation. Provide consistent moisture, aiming for one inch of water weekly, but avoid wetting the foliage to prevent disease. Mulch around the base to retain soil moisture and feed lightly with balanced fertilizer if growth slows.
Watch for aphids, spider mites, slugs, and Japanese beetles; inspect leaves regularly and remove infested parts or use insecticidal soap. Prevent fungal issues like fusarium wilt by ensuring good drainage and avoiding overhead watering. Harvest leaves when plants reach maturity, which takes about 68 days from sowing.
